Description
Technical field
The utility model relates to a kind of reinforcing oil well with mixing slurry equipment in batches, and particularly a kind of single jar of batch mixes slurry equipment.
Background technology
Mix slurry equipment in batches because institute's cement paste density fluctuation is less, its cement mortar can satisfy harsh cementing design required precision, more helps improving cementing quality, therefore more and more receives the concern of each elephant.Existing batch mixes the two slurry mixing tanks of the most employings of slurry equipment, and dynamical system drives a circular centrifugal pump, mixes the mixed slurry circulation and the pumping of two jars of slurry system realization by a cover.Existing two jar is mixed constructional problems of slurry equipment and shortcoming in batches and be: 1, adopt two slurry mixing tanks, the low-pressure manifold complexity not only causes pipeline mud to stop up easily, is unfavorable for that also manifold and slurry mixing tank clean after the operation; 2, circular centrifugal pump and centrifugal pump drive an only cover of hydraulic system, in case the individual component fault, complete equipment will shut down, and bury risk to well cementing operation; 3, be subjected to circular centrifugal pump restricted number, mix the slurry limited ability, mixed slurry speed is slow.
The utility model content
The purpose of this utility model provides a kind of single jar of batch and mixes slurry equipment, overcomes above-mentioned existing two jars and mixes in batches that the complicated easily obstruction of slurry equipment manifold, manifold and batch-handling mixers clean inconvenience, well cementing operation has a big risk, mixes slurry speed and waits defective slowly.
The utility model is achieved through the following technical solutions above-mentioned purpose: a kind of single jar of batch mixes slurry equipment, comprises fender bracket, instrument console, low pressure recycle manifold, blender, stirring motor, agitator, hydraulic system, dynamical system, circular centrifugal pump, slurry mixing tank, base, afflux groove; Only be provided with a slurry mixing tank, two circular centrifugal pumps are installed on the base side by side, form the fully independently centrifugal pump circulatory system of two covers, independently mix the slurry system thereby form two covers, and slurry mixing tank bottom afflux groove is near the circular centrifugal pump.Dynamical system drives the quadruplet hydraulic pump by transfer case, and hydraulic pump drives two centrifugal pump motors and two stirring motors respectively.Single jar of slurry mixing tank has two jars volume, and its volume 〉=16 cubic metre adopt camber, bottom to adopt inclined design all around.
The beneficial effect that the utility model is had compared with the prior art is: single jar of volume with two jars, by designing the i.e. big volume slurry mixing tank more than 16 cubic metres of twice, simplify manifold, and equipment cleans behind the convenient working, reduces the work operations amount; By increasing by a cover centrifugal pump circulatory system, improve and mix the slurry work capacity; The two cover centrifugal pump circulatory systems both can separate operaton, again can be standby each other, greatly reduced the well cementing operation risk that causes because of the circular centrifugal failure of pump.
